2 GENERAL DESCRIPTIONS

2.1 SPECIFICATIONS
This welding machine is a constant current generator built
using INVERTER technology, designed to weld with
covered electrodes and for TIG procedures (not including
cellulosic), with contact starting and high frequency.
IT MUST NOT BE USED TO DEFROST PIPES, START
ENGINES AND CHARGE BATTERIES.
2.2 EXPLANATION OF THE TECHNICAL SPECIFI-
CATIONS LISTED ON THE MACHINE PLATE.
This machine is manufactured according to the following
international standards: IEC 60974-1 / IEC 60974-10
(CL. A) IEC 60974-2/ IEC 60974-3 /IEC 61000-3-11 / IEC
61000-3-12. (see NOTE 2).
14
N°. Serial number, which must be indicated on any
type of request regarding the welding machine.
Three-phase static transformer-rectifier
frequency converter.Drooping characteristic.
MMA Suitable for welding with covered electrodes.
TIG Suitable for TIG welding.
U0. Secondary open-circuit voltage
X. Duty cycle percentage. % of 10 minutes during
which the welding machine may run at a certain
current without overheating.
I2. Welding current
U2. Secondary voltage with current I2
U1. Rated supply voltage
1~ 50/60Hz 50- or 60-Hz three-phase power supply
I1 max. This is the maximum value of the absorbed
current.
I1 eff. This is the maximum value of the actual current
absorbed, considering the duty cycle.
IP23S Protection rating for the housing.
Grade 3 as the second digit means that this equipment
may be stored, but it is not suitable for use
outdoors in the rain, unless it is protected.
S
Suitable for hazardous environments.
Note:
1- The machine has also been designed for use in
environments with a pollution rating of 1. (See IEC 60664).
2- This equipment complies with IEC 61000-3-
12 provided that the maximum permissible system
impedance ZMAX is less than or equal to 0,065 Ω (Art.
381) - 0,057 Ω (Art. 394)- 0,045 Ω (Art. 395) - 0,024 Ω (Art.
396) at the interface point between the user's supply and
the public system. It is the responsibility of the installer or
user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the
equipment is connected only to a supply with maximum
permissible system impedance ZMAX less than or equal
to 0,065 Ω (Art. 381) - 0,057 Ω (Art. 394)- 0,045 Ω (Art. 395)
- 0,024 Ω (Art. 396).
2.3 DESCRIPTION OF PROTECTION DEVICES
2.3.1 Thermal protection
This machine is protected by a temperature probe, which
prevents the machine from operating if the allowable
temperatures are exceeded. In these conditions the fan
continues to operate and display screen A shows the
message Err. 74. .
3 INSTALLATION
Make sure that the supply voltage matches the voltage in-
dicated on the specifications plate of the welding machine.
When mounting a plug, make sure it has an adequate ca-
pacity, and that the yellow/green conductor of the power
supply cable is connected to the earth pin.
The capacity of the overload cutout switch or fuses installed
in series with the power supply must be equivalent to the
absorbed current I1 of the machine.
